본 연구는 평택항을 통항하는 선박의 항해 안전을 확보하기 위해 교통안전특정해역 설정의 필요성을 정량적인 데이터로 제시하고자 하였다. 연구 비교 대상 6개 항만과 평택항과의 안개 일수, 도선 거리, 대형선 입항 척수, 조업 어선 척수를 비교 분석하였다. 연구결과 평택항은 잦은 시계 제한의 영향을 받는 역 조건의 가운데 부산, 부산신항, 울산, 포항항보다 약 3.5 ~ 6배 더 긴 도선 구간을 항해 해야한다. 특히 어장이 형성되는 5 ~ 7월에는 통항로에 위치한 35척의 조업 어선을 피하기 위해 대형선이 역주행하는 상황이 발생하여 상대 선박과의 충돌 위험을 갖는 교통 환경임을 확인하였다. 따라서 평택항 접근수역에 교통안전특정해역으로 설정한다면, 대형선이 조업 어선 보다 법적 우위를 갖게 되므로 통항 안전성을 확보할 수 있을 것으로 판단된다.

Marine casualties originated from fishing vessels occupied about 71.2% of the whole marine casualties in Korea from 2008 to 2014, which has not changed much for a long time. Therefore, a pragmatic counterplan to decrease in casualties in fishing vessel is indispensable for reduction of marine casualties in Korea. Since the casualties occurred by fishing vessels may incline to a specific type of casualties according to the difference in the operating type; in this paper, 11 fishing types which occurred casualties frequently in numbers and occupied ratio were selected. Since the most frequent occurring casualties in fishing vessels were from collisions and fire explosion in statistics from KMST (2008~2014), the study focused on them. The collision is given a great deal of weight in all the casualties mostly due to the negligence of duty regardless of the job types. Gill netter, trap fishing boat, jig boat, multiple fishing boat and stow netter have their own specific causes of casualties in collision according to the operating types. The cause of fire explosion was mainly due to poor inspection and maintenance the electric cord. For this reason, it may be necessary for an operator to make strict precaution on the other vessels under way systematically, keep the regulation for preventing collisions, and for an engineer on watch to make a check the electricity periodically to reduce the fire explosion.

The electro-hydraulic servo winch system built in a automatic tension control equipment was designed with a latent need for an advanced system in fishing operations of the inshore and coastal fishing vessels. In order to keep the constant tension condition of warp under loading, a tension control circuit was added to the servo winch system.The dynamic performance in the open loop behaviour of the designed winch system was investigated and its applicability was tested for various possibilities of load using a load generator especially developed in order to this study.The mechanical characteristics of this system is different from that of a conventional type, that is, the tension, length, line speed and drum revolution can be automatically controlled by the information from various sensors, such as torque, rpm and pressure transducers. from the experiment results, it was verified that the servo winch system has very good output and tracking behaviour for the control input signals in different operating conditions though overshoot of out 8% in the transient characteristics of torque under the load though a overshoot of about 8% in the transient characteristics of torque under the load condition can be observed when the opening of servo valve, adjustable by the input voltage between - 10 V up to 10 V, changed suddenly.Consequently, the improved fishing winch system can be effectively used as the automatic shooting and hauling equipment of low cost for small inshore and coastal fishing vessels which engage in net fishing.

Marine casualties originated from fishing vessel occupied about 70% of the whole marine casualties in Korea from 2001 to 2010, this ratio was not much changed as it was before. Therefore a pragmatic counterplan to decrease of casualties in fishing vessel is indispensable for reduction of the nationwide marine casualties. But since the casualties occurred by fishing vessel may have a different causes and counterplan according to the operating type of it, in this paper, fishing vessels classified into 12 types by operating method and inspected the causes and counterplan for that. The operating type of fishing vessel occurred the specific casualties more were jig boat in collisions and fire explosion, trap fishing boat, mixed fishing boats and inshore gill netter in collisions, stow netter in machinery damages and capsizing, offshore gill netter in machinery damages, fish carrier in collisions. It must be emphasized that the higher ranked types of vessels, especially jig boat have to take special care to the approaching vessels under way, trap fishing boat to rear look out and mixed fishing boat must keep on safety speed and be taken an education for advance the skill of operating radar as well. For all 12 types of fishing vessel, it is necessary for an operator to make strict precaution on the other vessel under way systematically and keep the regulation for preventing collisions, and for an engineer on watch to make a check the electricity and the engines periodically for reduction the fire explosion and machinery damages.

Marine casualties of fishing vessels were analyzed to reduce the sacrifice of human life using data of the Korean Maritime Safety Tribunal from 1995 to 2004 in Korea. The occurred number of fishing vessel casualties were likely to be higher portion than non-fishing vessels, but the occurring ratio of fishing vessel casualties were marked 2.96 times lower than that of non-fishing vessel casualties. The occurring ratios of bigger fishing vessel casualties were higher than smaller ones. Most marine casualties were resulted from the human factors such as poor watchkeeping, negligent action for engine and etc. The trend of marine casualties showed that the machinery damage hold the first and collision accidents took the second, but on a point of cause of them, operating errors took first and poor handling or inspection of machinery held the second place. Because those two casualties took major portion, and very important problems for safety of fishing vessels, so we ought to try to reduce the factors before everything else. In addition, since collision, sinking and capsizing in marine casualties have led to death, missing and injury of lives, it is necessary for navigation operators to take more educations and training intended to reduce the marine casualties systematically and continuously.

In contemporary society, shipping and fishery industry tend to use Japanese language or Japanese style terminology extravagantly. It becomes a reason of preventing the communications between crews who have been working for many years and the beginners in the ships. Also the crews cannot easily understand the contents of the manuals that is explained in only Korean language. For this reason, the foreign employee have to study Japanese style terminology before begin start their work. I strongly believe that this is one of the major national contempt. It is reasonable to expel Japanese style terminology from the vessel if possible to enable free communications to each other. I inspected and examined about purification of 125 Japanese style terminology that is already examined in the fishing vessels 11 years ago. So, I expect this paper is a research for the eradication of the Japanese style terminology in the Korean fishing vessels.

In recent 5 years, the 70 percent of the ship's accident was occurred in the fishing vessels, and most of them were the engine troubles and collisions. The capsizing accident was comparatively low portion of occupation, which took only 2 percent, but the scale of accident and the loss of lives and property are known very tremendous. In this paper, it was examined for the stability provisions of fishing vessels in domestic and international to reduce the capsizing of them. Also, it was made an analysis for the case of capsizing accidents to suggest the measures against the capsizing.
